腾讯云服务器搭建公网redis集群，springboot访问集群

男娘i 2022-01-29 07:19 313阅读 0赞

这简直是个坑，网上很多都系搭建在虚拟机的集群，按照那个的结果就是集群搭建成功了但是SpringBoot程序访问不了集群。

1.服务器上安装纯净的redis，在/usr.local/redis下，配置文件在/usr/local/redis/ets/redis.conf

2.修改安装的redis的配置文件

cd /usr/local/redis-cluster

mkdir bin

cd /usr/local/redis-3.2.9/src

![20190521134225654.png][]

cp mkreleasehdr.sh redis-benchmark redis-check-aof  redis-cli redis-server redis-trib.rb /usr/local/redis-cluster/bin

![20190521134240409.png][]![20190521134304597.png][]

cp -r /usr/local/redis    /usr/local/redis-cluster/9001

![20190521134358100.png][]

port 9001（每个节点的端口号）

![2019052113443738.png][]

dir /usr/local/redis-cluster/9001/data/（数据文件存放位置）：conf文件最后添加：

![20190521134507994.png][]

pidfile /var/run/redis\_9001.pid（pid 9001和port要对应）

![20190521134923829.png][]

cluster-enabled yes（启动集群模式）

![20190521134949461.png][]

cluster-config-file nodes-9001.conf（9001和port要对应）

![20190521135007541.png][]

cluster-node-timeout 15000

![20190521135038621.png][]

appendonly yes

![2019052113510183.png][]

我们已经完成了一个节点了，其实接下来就是机械化的再完成另外五个节点，其实可以这么做：把 9001 实例 复制到另外五个文件夹中，唯一要修改的就是 redis.conf 中的所有和端口的相关的信息即可，其实就那么四个位置。开始操作，看图：

\\cp -rf /usr/local/redis-cluster/9001/\*   /usr/local/redis-cluster/9002

\\cp -rf /usr/local/redis-cluster/9001/\*   /usr/local/redis-cluster/9003

\\cp -rf /usr/local/redis-cluster/9001/\*   /usr/local/redis-cluster/9004

\\cp -rf /usr/local/redis-cluster/9001/\*   /usr/local/redis-cluster/9005

\\cp -rf /usr/local/redis-cluster/9001/\*   /usr/local/redis-cluster/9006

修改 9002-9006 的 redis.conf 文件

其实非常简单了，你通过搜索会发现其实只有四个点需要修改，我们全局替换下吧，进入相应的节点文件夹，做替换就好了。

vi /usr/local/redis-cluster/9002/redis/etc/redis.conf

在命令模式下：输入冒号粘贴下面命令后按enter即可，保存退出，发现四个地方被替换了

%s/9001/9002

其实我们也就是替换了下面这四行：

port 9002

dir /usr/local/redis-cluster/9002/data/

cluster-config-file nodes-9002.conf

pidfile /var/run/redis\_9002.pid

对9003-9006按照上面的方法一次替换相应的9001为对应的端口

vi /usr/local/redis-cluster/9003/redis/etc/redis.conf

vi /usr/local/redis-cluster/9004/redis/etc/redis.conf

vi /usr/local/redis-cluster/9005/redis/etc/redis.conf

vi /usr/local/redis-cluster/9006/redis/etc/redis.conf

%s/9001/9002

%s/9001/9003

%s/9001/9004

%s/9001/9005

%s/9001/9006

开启腾讯云的端口：9001-9006和19001-19006

启动9001-9006六个节点
    /usr/local/redis/bin/redis-server  /usr/local/redis-cluster/9001/redis/etc/redis.conf
    /usr/local/redis/bin/redis-server  /usr/local/redis-cluster/9002/redis/etc/redis.conf

### **安装集群所需软件** ###

redis源码里有redis-trib.rb脚本，需要使用这个脚本搭建集群，脚本执行需要使用 ruby 命令，所以我们需要安装 ruby 和相关接口。

yum install ruby

yum install rubygems

上传文件：redis-3.2.1.gem（随便哪个文件夹）运行命令：gem install -l redis-3.2.1.gem

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NsNzIzNDAx_size_16_color_FFFFFF_t_70 5][]

集群环境测试：

/usr/local/redis-cluster/bin/redis-trib.rb create --replicas 1  xxxx:9001 xxxx:9002 xxxx:9003 xxxx:9004 xxxx:9005 xxxx:9006

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NsNzIzNDAx_size_16_color_FFFFFF_t_70 6][]

简单解释一下这个命令：调用 ruby 命令来进行创建集群，--replicas 1 表示主从复制比例为 1:1，即一个主节点对应一个从节点；然后，默认给我们分配好了每个主节点和对应从节点服务，以及 solt 的大小，因为在 Redis 集群中有且仅有 16383 个 solt ，默认情况会给我们平均分配，当然你可以指定，后续的增减节点也可以重新分配。

M: 10222dee93f6a1700ede9f5424fccd6be0b2fb73 为主节点Id

S: 9ce697e49f47fec47b3dc290042f3cc141ce5aeb xxxx:9004 replicates 10222dee93f6a1700ede9f5424fccd6be0b2fb73 从节点下对应主节点Id

目前来看，9001-9003 为主节点，9004-9006 为从节点，并向你确认是否同意这么配置。输入 yes 后，会开始集群创建。

就可以成功搭建集群了。

下面是搭建里遇到的问题：

1.出现：

![20190521140236325.png][]

要先启动6个redis才能用rubby构建集群

2.出现：

客户端连接的时候：

![20190521140617151.png][]

![20190521140628310.png][]

命令后加参数-c

![20190521140645768.png][]

其他结点访问：

![20190521140706325.png][]

3.关闭6个redis后重启，用rubby构建集群出现：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NsNzIzNDAx_size_16_color_FFFFFF_t_70 8][]

删除每个redis里的三个文件：

![20190521141012114.png][]

![20190521141026138.png][]

清除每个redis的数据，并且重置集群

出现：

说明没有开放19001-19006端口
